New Test Could Help Rule out Womb Cancer in Three Hours
NHS Forth Valley is the only site in Scotland to join a UK study into a diagnostic test which could help gynaecologists rule out womb cancer in three hours.
Most womb cancer usually starts in the lining of the womb and is also known as endometrial cancer.
Detecting the cancer marker MCM5 (Minichromosome Maintenance Complex Component 5) in the urine, could reduce the need for painful invasive procedures and biopsies in women suspected of having the disease.
The study will concentrate on women with post-menopausal bleeding, one of the most common symptoms of womb cancer. Diagnosis usually involves taking a biopsy from the lining of the womb which can be uncomfortable and even painful on some occasions. Many thousands of these tests are carried out in the UK each year however most women who undergo a biopsy will be found not to have endometrial cancer.
The non-invasive diagnostic test known as ADXGYNAE has been developed by UK based Arquer Diagnostics and has already been the subject of a study in Manchester. This showed that ADXGYNAE can accurately detect the presence of an endometrial tumour with a sensitivity of 87.8%. While this study enrolled patients already known to have endometrial cancer, in a prospective population this sensitivity would generate a 99.3-99.5% Negative Predictive Value (NPV), reinforcing that ADXGYNAE could be a valuable test for ruling out the disease.
Around 9,400 women are diagnosed with endometrial cancer, also known as uterine or womb cancer, in the UK each year. This makes it the fourth most common cancer in women in the UK – and the sixth most common globally – and the incidence and prevalence continue to rise each year. Over the past decade in the UK, uterine cancer incidence rates increased by 13%, in part fuelled by factors including increased rates of obesity, poor lifestyles and increased glycaemic load.
Unfortunately, because of a lack of diagnostic options, over 11 million invasive and painful tests are conducted globally each year, with just 3-5% resulting in a cancer diagnosis.
NHS Forth Valley Consultant Gynaecologist, Dr Sarah Barr, said; “I’m very excited that NHS Forth Valley is participating in this important study. Womb cancer is becoming increasingly common, but it usually presents early with unscheduled vaginal bleeding after menopause and is often very treatable when identified early.
“We really want to encourage anyone with these symptoms to come and have a check-up as soon as possible but we know gynaecological internal examinations are not always very easy and can sometimes mean that people are too scared to come and be seen. A reliable non-invasive test using a simple urine specimen could be a game changer for early diagnosis, both for improving outcomes for women with cancer, and for being able to reassure women experiencing potential symptoms when they don’t have cancer.”
Nadia Whittley, Chief Executive Officer of Arquer Diagnostics, added: “We know that there is a significant need to develop non-invasive and accurate diagnostic tests for endometrial cancer. In initial studies, our ADXGYNAE test is quick, painless and could rule out cancer with 99% accuracy and this should be validated by our ongoing studies currently being conducted. We are enthusiastic to be continuing with further clinical trials of ADXGYNAE in both the USA and Europe to bring this new diagnostic option to the Endometrial Cancer Pathway as quickly as possible.”
